ConvertWebViewToPdf

Library to create pdf file from webview

Add the following to your project level build.gradle:

    allprojects {	
        repositories {
	        maven { url "https://jitpack.io" }
        }
    }

Add this to your app build.gradle:

    implementation 'com.github.thefaisalurrehman:Webview-to-pdf:1.0.1'

Permission in Manifest

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

If your targetSdkVersion >= 24, then we have to use FileProvider class to give access to the particular file or folder to make them accessible for other apps. Add a FileProvider tag in AndroidManifest.xml under tag.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
...
<application
android:requestLegacyExternalStorage="true">
    ...
         <provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="com.package.name.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths" />
    </provider>
</application>
</manifest>

Then create a provider_paths.xml file in res/xml folder.

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
 <external-path name="external_files" path="."/>
</paths>

Before Create pdf check this permission for Android 11 devices.

 override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    // check permission is Granting
    if (requestCode == 1 && Environment.isExternalStorageManager()){
        //write create pdf code here
    }
}

Sample code :

                val fileName = "Test.pdf"
        val directory = ContextCompat.getExternalFilesDirs(
            context,
            Environment.DIRECTORY_DOCUMENTS + "/PDFTest/"
        )
        PdfView.createWebPrintJob(
            activity,
            webView!!,
            directory[0],
            fileName
        ) { path ->
            path?.let { it ->
                fileChooser(context,it)
            }
        }


        private fun fileChooser(context: Context, path: String) {
            val file = File(path)
            val target = Intent("android.intent.action.VIEW")
            val uri = FileProvider.getUriForFile(context, "com.package.name.fileprovider", file)
            target.setDataAndType(uri, "application/pdf")
            target.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
            val intent = Intent.createChooser(target, "Open File")
         try {
               context.startActivity(intent)
            } catch (var6: ActivityNotFoundException) {
             var6.printStackTrace()
         }
        }
